A system and methods are disclosed for automatic focus detection with relative threshold-aware cell visibility for a scrolling cell collection. The method includes identifying visible cells of a plurality of cells of a reference frame, the visible cells rendered in a graphical user interface (GUI) displaying at least a portion of the reference frame, determining, by a processing device rendering the GUI and for each visible cell of the visible cells, a distance value indicating a distance to a focus threshold in the reference frame that the visible cell has traveled since the visible cell became visible in the GUI, and modifying a behavior of the visible cells in the GUI based on the distance value of each of the visible cells.

 identifying the visible cells that have an absolute visibility percentage that exceeds a threshold visibility percentage; 
 selecting a determined number of the identified visible cells as focus cells based on a number of the focus cells designated for the GUI; 
 ordering the identified visible cells into ordered visible cells according to a priority sort order; 
 selecting the determined number of the ordered visible cells that are ordered highest as the focus cells; and 
 returning identification of the focus cells and the distance values of each of the visible cells; 
 wherein the priority sort order is based on at least one of a top-to-bottom direction, a bottom-to-top direction, a left-to-right direction, or a right-to-left direction. 
 
     
     
       9. The method of  claim 1  wherein modifying the behavior comprises applying the distance value to the visible cells to provide a color blending effect in the visible cells in accordance with a particular value of the distance value.
